Sorting associations in retrieveXPathQuery

I am trying to use retrieveXPathQuery to extract slected data and I need to sort the data. Howver that attributes that I want to sort on are associations. With normal attributes I am using the using the 'Proxie Object'.MemberName.'Attribute' to get the name of the field for the sorting map. When I debug the java I see the assoociation name coming up as RefereingObjectObject eg. Invoice_OrderLine. Will this actually be used as a sort parameter Thanks

If I remember correctly, you can use a String in the format


as sorting.
